You can select Periodic or Aperiodic operations. The bit tags were automatically categorized into Aperiodic Coils, and the registers to Aperiodic registers. In the next image, the Aperiodic tabs were selected when the struct was added. UniLogic opens the Add window, displaying the structs. Group ID allows you to run an entire group of operations.ĭesired operation type, and click the drop-down arrow under Add New Note that the ID parameters allow you to use Aperiodic Ladder elements to run the operations via your program. ![]() Note that you can also select several operands by holding down CTRL while clicking them and the right-clicking them. You can convert Periodic operations to Aperiodic, and vice versa. The next image shows Aperiodic operations. To prevent the operation from running, turn this bit OFF. To do this, assign a bit to the operation's Active parameter. Note that while the Active Periodic setting in Properties determines whether the master will run operations periodically, you can prevent an individual operation from running. The next image shows Periodic operations. UniLogic adds a row to the table.Ĭlick in fields to edit and make selections. Select the tab with the desired operation type, and click Add New Operation. You can create both Period and Aperiodic operations. The MODBUS operations you create are arranged in a table. Use this to set whether the MODBUS operations will run via Ethernet or serial port by clicking on the Communications drop-down arrow.Įnter the ID number of the slave to be accessed If this bit is ON, this slave will be accessed when MODBUS operations are run. This is described in the section below, Dropped Operations.įor each slave, add new operations as described below. The Queue options may be used in certain programs that rely on large quantities of data. The default is 500ms, click the field to edit the value.ĭetermines how long the controller will wait for a response from the remote slave. The range is 1-255.Īssign a name to help you identify the slave Use this to select the port for the MODBUS operations by clicking the drop-down arrow.Įnter the ID number of the slave to be accessed. You can suspend a specific operation from running via the operations' Active parameter. You must link a bit to this parameter failing to do so will result in a compilation error. Turn it OFF to suspend all Periodic operations for this slave. Turn it ON to run the Coil and Register Periodic operations according to the time interval you have set in the individual operation. This bit controls, for this particular slave, whether Periodic Operations run or not. MODBUS Slave Properties Window Parameters ![]()
